The power train control module on a Ford controls every aspect of the vehicle’s engine, transmission, clutch and electrical and fuel delivery. Without a properly working PCM, the Ford will not run. At times, you may want to perform a reset of the Ford PCM for basic troubleshooting. This can often resolve small issues that you may experience with the Ford.
Step 1: Open the hood of the Ford. Loosen the lock nut located on the negative battery cable connector with a socket and ratchet. Pull the connector off the negative battery terminal.
Step 2: Wait for 20 minutes while the PCM bleeds off the electricity it stores for backup power. Once the power drains from the PCM, it resets.
Slide the negative battery connector onto the battery terminal and tighten the lock nut with the socket and ratchet. Items you will need: Socket set
